Reading Comprehension:


The Falcon Heavy is capable of lifting 140,000 pounds to low-Earth orbit, more than any other rocket today. Because all three boosters are to be recovered to fly again, a Falcon Heavy launch costs not much more than one by the company’s existing rocket, Mr. Musk said. SpaceX lists a price of $90 million for a Falcon Heavy flight, compared with $62 million for one by Falcon 9, a bargain in the context of spaceflight. SpaceX has booked upcoming Heavy flights for Arabsat, a Saudi Arabian communications company, and the United States Air Force.

Although delayed by high-altitude winds, the countdown proceeded smoothly, without any of the glitches that have bedeviled other maiden launches of new rockets.  The Heavy roared to life, a plume of smoke and steam shooting sideways from the launchpad. It rose from the pad, with an impossibly bright glare of 27 engines beneath it. Then a thunderous roar, traveling at the speed of sound, rolled over the spectators.
